I think people are misunderstanding your point here. This is an evolutionary advantage because it facilitates the passing of skills and knowledge. Because of that it is, like you said, directly linked to why we get old instead of, for instance, having two dozen kids and dying at 20 like rabbits might. Folks that kept grandparents stayed alive more than ones that didn’t.
I know for a fact that’s not true because when I was in Japan I saw some wild monkeys being cared for and they specifically had signs on the all showing the family trees of the different monkeys being cared for and explaining how the families all worked
One of the things mentioned was that the grandparent/parent/child units would all work together more closely with each other than non-family members, though they were more collaborative overall than humans
Also elephants come to mind as a non primate mammal
Yes, they can help care and give wisdom. Directly linked to why we get that old.
Edit: apparently, other primates have grandparents too.

Thanks, you explained it better.
